Classic Complement

Choosing Polycor Hardscapes and Masonry window sills add the classic complement to your architectural design. Available in Indiana limestone, granite, and marble, sills can be easily sawn to length and shaped on site by masonry contractors. Being that they are 100% natural stone they do not show any exposed aggregates or loss of color when the interior is exposed after cutting – an inherent benefit to using real stone.
